FRANK F. PIERCE, OF BRODHEAD, WISCONSIN.

PUMP.

SPECIFICATION forming part of Letters Patent No. 253,760, dated February 14, 1882.

l Application filed December 9, 1881. (No model.)

.To all whom it may concern Be it known that l, FRANK F. PIERCE, of Brodhead,in the county of Green and State of Wisconsin, have invented certain new and useful Improvements in Pumps; and I do hereby-declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specilication, in which- Figure l is a view of the pump in elevation; Fig. 2, a longitudinal sectional view of the same Fig. 3, a perspective view otl the base; Fig. 4', a similar view of a bolt and nut ernployed in securing the parts together.

Similar letters of reference in the several figures denote the same parts.

rllhis invention relates particularly to that class of pumps that are adapted to be operated by hand as well as bya windmill or other power 5 and it consists in certain novelties of construction, which I will tirst describe, and then point out particularly in the claims.

In the accompan `yin gdrawin gs, A represents the stock ofthe pump, constructed preferably of metal, and having a spout, A', about midway ot its length.

B is a metal base, upon which the stock rests, a shoulder, a, being formed upon the stock, so that the latter shall fit into as well as upon the base, as shown in Fig. 2. The base has an annular ange, b, projecting down from the upper portion, upon which the stock rests, said llange forming an annular recess, b', behind it,

as shown. A series of bolts, c, having hooked lower ends, c', pass up through holes in the lowerangeofthepump-stock,andtheirhooked ends engage with the depending llange b and project into the annular recess b', as shown in Fig. 2, while their upper screw-threaded ends are provided with nuts d. A slot or nick, c2, is made in the upper end ot' each of the bolts, in order that the bolt may be held in proper position by a screw-driver or other tool inserted in said slot while the nut is being screwed tightly down. The upper end of the pumpstock is provided with a depending an ge similar to that on the base, and the top or cap l) is shouldered and lits the top of the stock, and is held by another series of the hooked bolts, as clearly shown in Fig. 2. By this manner of connecting the cap and base to the stock the stock is enabled to be turned to the right or left on its vertical axis, after loosing the nuts on the several bolts, so as to bring the spout in any desired position with respect to the operating-handle and fulcrum, or vice versa.

The cap D is provided with an arm, D', which extends upward and inward, and is perforated for the passage of', and forms a guide for, the plunger or piston rod E. It is also provided with a lateral slotted arm, D2, which forms the guide and lateral support of the oscillating fnlcrum F ofthe handle Gr. The said fuloruln has a perforation in its lower end, and is mounted upon a bolt,f, between two lugs, b2 b2, on the base B, so as to turn freely, while its upper end extends up through the slot in the arm D2,

and is bifurcated to receive the operating-han- 'dle G, and perforated for the passage ot' the pivot-bolthot'the handle, as shown. The short arm of the handle is connected to the pumpplunger at h'.

In order that the leverage applied by the handle may be varied, it is provided with a series of pivot'holes, h2, and by shifting the pivot-bolt from one to the other of these holes the leverage may be increased or diminished, as desired.

In operation the fulcrum F vbrates back and forth, being guided by the slotted arm D2, while the plunger works up and down in a true vertical line, being guided by the arm D', as well as by the cap.

It will be seen that by connecting the fulcrum to the base instead of to the stock the latter is relieved of all-strain and weight.

All the joints of the pump being tight, the upper part of the stock forms an air-chamber which is usel'nl in securing a uniform How.

The upper extended end of the plunger is adapted to be connected to the pitman of a windmill or other power, and when so connected the handle may be disconnected, if desired. v

I claim as my inventiou- 1. The combination, with the pump-stock having the depending annular flange at its-upper end, of the base having the depending annular flange, the cap carrying the guide for the fulcruxn, the hooked bolts and nuts for unitiu the stock to the base and to the cap, and the haudleand fulcrum, the latter hinged to the base, the whole arranged and adapted for adjustment substantially as described.

2. The cap having the upwardly and inl wardly extending arm,forming a. guide for the '5 plunger, and the laterally-slotted arm for guiding and supporting` laterally the fulerum7 substantially as described.

3. The combination, with the parts to be FRANK F. PIERCE.
